virtual function

In Java a function can be made virtual by just attaching the keyword virtual to implement polymorphism.Eg:- class any { int a; float b; virtual void show() { System.out.println("a="+a+"\n b="+b); } } class many extends any { int a1; float b1; void show() { Syatem.out.println("a="+a+"\n b="+b); } public static void main() { any *ptr; many *ptr1; ptr=&ptr1; ptr->show(); ptr->show(); } }
